Product Details

The SPEC SB074 Stage 4 Clutch Kit is engineered for heavily modified, high-performance engines where maximum torque capacity, instantaneous engagement, and reduced rotating mass are the top priorities. This is a purpose-built competition clutch designed for drivers who demand the absolute limit of clutch performance on the track or strip.

Note: Due to its aggressive engagement characteristics, this kit is not recommended for street use. It is intended for competition and dedicated performance applications only.

Key Features:

  • High clamp load pressure plate for maximum clamping force and torque transfer
  • 3, 4, or 6 puck carbon semi-metallic friction disc for aggressive, instantaneous engagement and high heat resistance
  • High torque rigid hub and carrier assembly for direct, efficient power transfer
  • Lightweight design to reduce drivetrain rotational mass and improve throttle response
  • Includes release bearing and installation tool kit

Ideal Racing Disciplines:

  • Drag Racing
  • Drifting
  • Road Racing
  • Rallye
  • Pulling
  • Circle Track

SPEC clutches are manufactured to exacting tolerances and engineered specifically for performance motorsport. The Stage 4 represents the top tier of the SPEC lineup, delivering uncompromising grip and engagement for competitors who cannot afford clutch slip under maximum load.
